Description

Technical Field

[0001] This utility model relates to the field of brake disc processing fixtures, and more specifically, to a wheel-mounted brake disc processing fixture with anti-deviation function. Background Technology

[0002] Wheel-mounted brake discs are one of the core components of a vehicle's disc braking system. They are directly mounted on the wheel hub and work with the brake calipers and brake pads to decelerate or stop the vehicle. In mass production, the performance of each brake disc must be strictly uniform (such as thickness and parallelism). If manual clamping is relied upon, slight differences may occur in each positioning, resulting in inconsistent product specifications after processing.

[0003] Among them, the patent with announcement number CN217317048U discloses a wheel brake disc processing fixture, which is provided with a base plate, and a virtual circle is formed on the upper surface of the base plate; multiple columns supporting the wheel brake disc away from the upper surface of the base plate are evenly distributed on the virtual circle, and multiple sets of positioning block assemblies are also arranged in the circumference of the virtual circle; wherein, the positioning block assembly has two positioning blocks that can contact the inner diameter and outer diameter of the heat dissipation fins on the lower surface of the wheel brake disc, and a positioning rod component connecting the two positioning blocks, and at least one positioning block in each set of positioning blocks is slidably connected to the base plate;

[0004] In use, the base plate supports the wheeled brake disc away from the upper surface of the base plate via columns, and multiple sets of positioning block assemblies hold the heat dissipation fins from the lower surface of the wheeled brake disc, thus fixing the wheeled brake disc to the base plate and restricting its radial displacement. Secondly, threaded holes are provided on the columns, and the axial displacement of the wheeled brake disc is restricted by the connection between the threaded holes and the connectors, pressing the wheeled brake disc firmly against the base plate. However, this structure cannot achieve simultaneous clamping of the brake disc during use, which can easily lead to misalignment during clamping, thereby affecting machining accuracy. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wheel brake disc machining fixture with anti-deviation function, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a wheel brake disc processing fixture with anti-deviation function, including a mounting plate, wherein a linkage clamping assembly is provided on the mounting plate;

[0007] The linkage clamping assembly includes an inner liner plate disposed in the middle of the mounting plate, and the top of the inner liner plate is provided with several clamping rods with adjustable angles.

[0008] Each of the clamping rods has a sliding groove at one end and a slide rail on one side. The clamping rods are all distributed around the circumference of the axial center of the inner liner, and one end of each adjacent clamping rod extends through the sliding groove to the slide rail and is slidably connected to the slide rail.

[0009] Optionally, in one possible implementation, the clamping rod extends to the top of the mounting plate at the end away from the slide groove. The clamping rod is rotatably connected to the mounting plate. The upper surface of the inner liner is provided with a plurality of mounting grooves, and each mounting groove is located at the bottom of the corresponding clamping rod. Traction blocks are slidably connected in the plurality of mounting grooves, and a vertical shaft is fixedly provided at the top of each traction block. The vertical shaft is inserted into the bottom of the clamping rod and rotatably connected to the clamping rod. A torsion spring is sleeved on the outside of the vertical shaft. The top and bottom of the torsion spring abut against the traction block and the clamping rod, respectively. A motor is installed at the bottom of the mounting plate by bolts, and the output end of the motor extends to one of the clamping rods.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] Through the design of the linkage clamping assembly, multiple clamping rods are distributed around the circumference of the inner liner disc, and adjacent clamping rods are slidably connected to the slide rail via grooves to form a linkage structure. When the motor drives one clamping rod to move, the remaining clamping rods can adjust their angles simultaneously to achieve uniform circumferential clamping of the brake disc. This avoids the brake disc offset problem caused by uneven clamping force in traditional fixtures, significantly improving the positioning stability during processing. At the same time, it can adapt to wheel-mounted brake discs of various diameters, eliminating the need to customize fixtures for different specifications of brake discs and reducing production costs.

[0012] The torsion spring not only provides preload to the clamping rod, but also assists the clamping rod in quickly resetting when the brake disc is released, further shortening the loading and unloading interval and improving the efficiency of mass production. The sliding connection structure between the traction block and the mounting groove, combined with the rotational connection between the vertical shaft and the clamping rod, makes the adjustment of the clamping rod more flexible and smooth, ensuring that a stable force state can be maintained when clamping brake discs of different specifications.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment discloses a wheel brake disc machining fixture with anti-offset function, which aims to achieve synchronous clamping of the wheel brake disc through a linkage clamping assembly, avoiding offset caused by uneven force during machining. The specific structure is as follows:

[0021] As attached Figure 1 As shown, the fixture includes a mounting plate 1, which can be machined from steel plate to provide a stable mounting reference. A linkage clamping assembly is provided on the mounting plate 1, which is the core actuator of the fixture.

[0022] The specific structure of the linkage clamping assembly is as follows:

[0023] As attached Figure 3 As shown, an inner liner plate 2 is provided in the middle of the mounting plate 1, and the axis of the inner liner plate 2 coincides with the axis of the mounting plate 1.

[0024] As attached Figure 2 As shown, the top of the inner liner plate 2 is provided with several angle-adjustable clamping rods 3, and each clamping rod 3 is circumferentially distributed along the axis of the inner liner plate 2 to ensure uniform force distribution.

[0025] As attached Figure 2As shown, each clamping rod 3 has a groove 4 at one end, and a slide rail 5 is provided on one side of each clamping rod 3. The slide rail 5 has a convex structure and is clearance-fitted with the groove 4. In adjacent clamping rods 3, the groove 4 of one clamping rod 3 extends to the slide rail 5 of the other clamping rod 3, and the two are slidably connected to achieve linkage.

[0026] As attached Figure 3 As shown, the end of the clamping rod 3 away from the slide groove 4 extends to the top of the mounting plate 1 and is rotatably connected to the mounting plate 1 via a shaft, ensuring that the clamping rod 3 rotates smoothly without radial movement.

[0027] As attached Figure 4 As shown, the upper surface of the inner liner plate 2 has several mounting grooves 6, which can be T-shaped grooves. Each mounting groove 6 is located directly below the corresponding clamping rod 3 and is distributed radially along the inner liner plate 2. A traction block 7 is slidably connected in each mounting groove 6. The traction block 7 can be T-shaped and fits the mounting groove 6 with a clearance.

[0028] As attached Figure 4 As shown, each traction block 7 has a vertical shaft 8 welded and fixed to its top. The top of the vertical shaft 8 is inserted into a pre-set shaft hole at the bottom of the clamping rod 3 and is rotatably connected to the clamping rod 3 through a ball bearing. A torsion spring 9 is sleeved on the outside of the vertical shaft 8. The top of the torsion spring 9 abuts against the bottom of the clamping rod 3, and the bottom abuts against the top of the traction block 7. In the initial state, the torsion spring 9 is in a slightly compressed state, providing preload.

[0029] As attached Figure 1 As shown, a motor 10 is bolted to the bottom of the mounting plate 1. The motor 10 can be a Panasonic MSMD022G1U servo motor. Its output shaft extends to the bottom of one of the clamping rods 3 via a flexible coupling and is keyed to the clamping rod 3.

[0030] The specific working principle is as follows: under the preload of the torsion spring 9, each clamping rod 3 is in an open state.

[0031] When it is necessary to clamp the wheel-mounted brake disc, the wheel-mounted brake disc is placed between each clamping rod 3. The clamping rod 3 connected to it is driven by the motor 10 to rotate clockwise around the bearing, thereby securing it. Figure 2 Taking a perspective example, since adjacent clamping rods 3 are slidably connected to the slide rail 5 and the slide groove 4, the rotation of the clamping rod 3 will push the adjacent clamping rods 3 to rotate synchronously clockwise through the slide groove 4, and the included angle of each clamping rod will gradually decrease, converging towards the center. At the same time, the rotation of the clamping rod 3 will pull the traction block 7 to slide inward along the mounting groove 6 through the vertical shaft 8, and the torsion spring 9 will be further compressed, storing elastic potential energy. When the inner wall of the clamping rod 3 is in close contact with the outer peripheral wall of the brake disc, the contact force can be controlled by the current feedback of the motor 10. If the threshold is set to 50N, the motor 10 will stop rotating, and the brake disc will be clamped evenly from the circumference by the clamping rod 3, achieving anti-deviation positioning.

[0032] After processing, the motor 10 drives the clamping rod 3 to rotate counterclockwise, the torsion spring 9 releases its elastic potential energy, pushes the traction block 7 to slide outward, and drives the clamping rod 3 to open synchronously until it returns to its initial state. At this time, the processed brake disc can be removed.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
